Strange Phenomena - the Morrabio in Sicily
By yesterday morning it had been blowing 7-8 from the SE for almost 24 hours. It was wearing, and as I stepped onto the pontoon I noticed that the water was dirty and very turbulent - in fact there was a strong current swirling through the pontoons. As I looked S towards the control tower - see pic - I could see the water level dropping as I watched. In minutes it dropped a foot, and then started coming up again. This continued for most of the morning. I estimate that the amplitude was about 6" (12" trought to peak) with a period of 8-10 minutes. I believe the phenonmenon is called the Morrabio (spelling?), and occurs in certain pressure conditions between Pozzallo and Sciacca.
